Connecting the JCS 1200 DC Platform to DC Power
Ensure that the voltage across the DC power source cable leads is 0 V and that
there is no chance that the cable leads might become active during installation.
Verify that a licensed electrician has attached the cable lugs to the power cables.
Switch both circuit breakers on the power supply faceplate to the off position
( O ).
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis.
Remove the terminal cover for each terminal.
Attach the lugs on the DC source power cables to the terminal studs, making
sure the cables are not touching or in the way of any JCS 1200 platform
components. When connecting a cable lug to each stud, install a flat washer on
the stud, install the cable lug, install a flat washer, install a split washer, and then
install a nut (see Figure 28 on page 64). Torque the wiring terminal nuts to
13.3 lb-in. (1.5 Nm).
a. Attach the positive (+) DC source power cable lugs to the
terminals.
Attach the negative (–) DC source power cable lugs to the
b.
terminals.
